Description:
Phytoplankton blooms characterize temperate ocean margin zones in spring. We investigated the bacterioplankton response to a diatom bloom in the North Sea and observed a dynamic succession of populations at genus-level resolution. Taxonomically distinct expressions of carbohydrate-active enzymes (transporters; in particular, TonB-dependent transporters) and phosphate acquisition strategies were found, indicating that distinct populations of Bacteroidetes, Gammaproteobacteria, and Alphaproteobacteria are specialized for successive decomposition of algal-derived organic matter. Our results suggest that algal substrate availability provided a series of ecological niches in which specialized populations could bloom. This reveals how planktonic species, despite their seemingly homogeneous habitat, can evade extinction by direct competition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teeling, Hanno -- Fuchs, Bernhard M -- Becher, Dorte -- Klockow, Christine -- Gardebrecht, Antje -- Bennke, Christin M -- Kassabgy, Mariette -- Huang, Sixing -- Mann, Alexander J -- Waldmann, Jost -- Weber, Marc -- Klindworth, Anna -- Otto, Andreas -- Lange, Jana -- Bernhardt, Jorg -- Reinsch, Christine -- Hecker, Michael -- Peplies, Jorg -- Bockelmann, Frank D -- Callies, Ulrich -- Gerdts, Gunnar -- Wichels, Antje -- Wiltshire, Karen H -- Glockner, Frank Oliver -- Schweder, Thomas -- Amann, Rudolf -- New York, N.Y. -- Science. 2012 May 4;336(6081):608-11. doi: 10.1126/science.1218344.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Marine Microbiology, Celsiusstrasse 1, 28359 Bremen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556258" target="_blank"〉PubMed〈/a〉
